AMM ON IA-SATURATOR.

Specification of Letters Patent.

Application filed April 10, 1915. Serial No. 20,448'.

To all whom z't may concern.'

Be it known that I, AUGUST F. HILLEKE, a citizen of the United States, residing at Ensley, in the county of J eiferson and Sta-te of Alabama, have invented certain new and useful Improvements in Ammonia-Satura tors, of which the followlng is a specication.

M1517 invention relates to the construction of t the sulfate salt is formed by the contact of the ammonia carryinggas with sulfuric acid. In the operation of such a device the gas is brought into intimate contact with the acid by being caused to pass under baffle plates which project downward into the acid and a difficulty has been experienced owing to thefact that the salt is quickly formed at the points lwhere the gas passes under the baiiies and is built up in masses which adhere to the baffle plates` and obstruct the gas way.

The object of my improvements is to remedy this difliculty and provide for the.

free-passage of the all times.

rIhe invention will be best understood by reference to the accompanying drawings illustrating an embodiment thereof, Figure l showing a vertical section on the line 1-1, Fig. 2, and Fig. 2 showing a plan view sectioned on the line 2`2, Fig. l.

Referring to the drawings, A, indicates 'the shell of the saturator, B, are gas inlets through which the ammonia carrying gas enters the saturator, entering first a gas way, G, the outer wall of which is the outer wall of the saturator and its inner wall a cylindrical baffle, C, the lower edge of which lies below the level of the acid in the saturator. After entering'` the saturator the @as is brought into Contact with the acid by being caused to pass under the serrated edge gas into the satura'tor at ucpies of this patent may be obtained for ve cents each, by addres Washington, D. C.

surface thereof.

of the cylindrical baffle, C, and afterward, preferably, under a second similar baffle, C.

To the outer, upper surface of the baiie, l, is secured an acid feed trough, D, which extends around the baiiie. A similar acid feed trough, D, is secured to the baffle, C. The feed troughs, D, are, preferably, provided with serrated edges, lso that the acid will be fed downward in fine streams, and are supplied with acid through the feed pipes, rl, d.

n the operation of the device the salt formed bythe passage of the gas through the acid tends to build up in masses on the lower edges of the ba es., C, C The fresh acid required for the maintenance of the 0peration is fed, as called for, into the troughs, D, D, and thence Hows downward over the surfaces of the baffles. Thus it comes into contact with any salt that may have formed upon the baflie and cuts the same away causing it to fall down to the bottom of the saturator, out of the gas way. In this manner a free supply of gas to the saturator is maintained at all times.

hat I claim as new by Letters Patent is:

'In a saturator the combination with a cylindrical baffle ofba circular acid supply trough secured to the upper part of the baiie, and adapted to deliver acid upon the 2. In a saturator, the combination of a gas way, a baffle and an acid feed trough located in the gas way and adapted to deliver acid contiguous to the surface of the baffle.

In testimony whereof, I have hereunto subscribed my name, this th day of April AUGUST F. HILLEKE. Witnesses:
